A well in Harrison County, West Virginia, was stimulated with a 3 foot GasGun. This is a cased hole completion in a Devonian sandstone formation at a depth of 2987 feet. Production increased from 5 BOPD to 40 BOPD. After 6 months, production was still holding at post stimulation levels.

A well in Harrison County, West Virginia, was stimulated with a 3 foot GasGun. This is a cased hole completion in a Devonian sandstone formation at a depth of 2963 feet. Production increased from 5 BOPD to 15 BOPD. After 6 months, production was still holding at post stimulation levels.

Three injection wells in Wetzel County, West Virginia, were stimulated with the GasGun. These wells were completed open hole in a Devonian sandstone formation at an approximate depth of 3500 feet. Before the stimulations, injection rates ranged between 0 to 50 BWPD. After the GasGun stimulations, the injection rates increased in all 3 wells and now range from 100 to 150 BWPD . After 6 months, injection rates were still holding at their post stimulation levels.

A GasGun stimulation was conducted on a Salt Sand formation in Pleasants County, West Virginia. The formation was at 1380′ and was completed with a notched casing. Hydraulic fracturing in similar wells had not provided satisfactory results. The well was shot with an 8 foot GasGun at noon and was back on production in the late afternoon of the same day. Prior to the GasGun shot, the well had been making 28 MCF/D. Immediately following the shot production was logged at 50 MCF/D and leveled off at 40 MCF/D a week later.
